Error Opening File / Corrupted Dorico file from Cloud sync issues

Hi,

I’ve been working on a Dorico project that’s saved to a cloud service, and when I tried to open it today it gave me an “Error opening file” message. After trying to recover a saved version from both the cloud service and Dorico autosaves, they were all corrupted (until before my last work session on the file).

I’m attaching both the diagnostics report here. If anybody has any ideas about how to recover the file, I would be very relieved…
